Symmetrical communication portions formed in respective inner surfaces of arms of a lever extend from an inner end surface of a guide groove to an inner peripheral surface of a rotation hole. To connect the lever to the selected housing, the lever is moved parallel relative to the male housing in such a manner that rotation pins move along the respective guide grooves and communication portions until they are rotatably received in the respective rotation holes. Accordingly, there is no need to elastically deform the lever in order to attach the lever to the housing, and therefore, the burden on the operator is small because the two rotation pins are simultaneously guided to the respective rotation holes by the respective guide grooves. Therefore the attaching operation can be carried out easily and positively. After the lever is attached to the selected housing, another housing may be connected to the selected housing also using the communication portions of the lever.
A lever-type connector comprising a generally U-shaped lever having a guide groove of a generally volute shape formed in each of opposed inner surfaces of opposite end portions of said lever, said guide groove being open at one end to a side surface of said end portion, each of said opposite end portions having a rotation hole open to said inner surface, said lever being attached to a housing of said connector having rotation pins formed on respective opposite side surfaces thereof for rotatably fitting respectively in said rotation holes, and an inner end of each of said guide grooves being contiguous with a peripheral surface of a respective one of said rotation holes.
A connector comprising:
A connector comprising a housing and a lever that includes a main body and a pair of generally parallel extending arms each having an aperture, said lever being attachable via said apertures to rotation pins mounted on said housing, each of said arms including a proximal end connected to the main body, a distal end, and a groove in communication with a respective one of the apertures and extending from said distal end to said proximal end.
A method for assembling a lever-type connector having a first housing and a lever including a pair of arms each having an aperture, said lever being attachable via said apertures to pivot pins located on said first housing, said arms further comprising grooves extending from respective distal ends of said arms to said apertures, the apertures being positioned at proximal ends of the pair of arms, the method comprising:
